Severe pressure ulcers requiring surgery impair the functional outcome after acute spinal cord injury

The acute phase management of traumatic spinal cord injury (tSCI) with polytrauma: A narrative review

Introduction

Traumatic spinal cord injury (tSCI) is frequently observed in polytrauma patients.

Research question

What is the optimal strategy to manage tSCI in the setting of polytrauma?

Material and methods

This narrative review focuses on: 1) extraspinal damage control surgery and resuscitation, 2) the perioperative protection of the injured spine during emergency surgery, 3) imaging and timing of spinal surgery in polytrauma, 4) early interventions for skin, bowel and bladder, and 5) the multidisciplinary approach to tSCI polytrauma patients.

Results

Damage control resuscitation (DCR) and damage control surgery (DCS), aim to prevent/correct post-traumatic physiological derangements to minimize bleeding until definitive hemostasis is achieved. Spinal protection during emergency surgery is of paramount importance to reduce secondary insults to the injured spine. Imaging, especially magnetic resonance imaging (MRI), is useful for decision-making regarding surgical management of the injured spine. Early decompressive surgery (within 24 h from trauma) is associated with better neurological outcomes. Early consultation with a physical medicine and rehabilitation physician is beneficial to optimize recovery. A close collaboration between different medical specialties involved in the early management of tSCI patients with polytrauma is advisable to improve outcome.

Discussion and conclusion

This narrative review aims to collate basic knowledge regarding acute phase management of tSCI patients in the context of polytrauma. More evidence and data form well-powered studies are necessary in this setting.

Implementation and clinical impact of an interdisciplinary tool to promote skin integrity after flap surgery in Veterans with spinal cord injury

CONTEXT/OBJECTIVE

Pressure injury (PrI) recurrence is common among persons with spinal cord injury and disorders (SCI/D) who undergo reconstructive flap surgery for pelvic stage 4 PrI (S4PrI). This paper describes the development and implementation of the Minneapolis Spinal Cord Optimization, Rehabilitation and Empowerment (SCORE), a preoperative interdisciplinary tool for risk assessment and mitigation, and reports its effect on the one-year flap failure rate (significant breakdown).

DESIGN

Retrospective review.

SETTING

Minneapolis Veterans Affairs Health Care System (MVAHCS) SCI/D Center, a tertiary care center.

PARTICIPANTS

141 Veterans with SCI/D and pelvic S4PrI underwent 204 interdisciplinary assessments for flap surgery.

INTERVENTIONS

The Minneapolis SCORE was developed by the MVAHCS SCI/D Center and first implemented in 2012. The eight domains of the tool and continuous improvements in tool implementation for risk assessment and mitigation are described.

OUTCOME MEASURES

Per-year incidence rate of flap failures within one year of surgery from 2009 to 2019.

RESULTS

48.3% (28/58) of S4PrI assessments during 2009-2011 (pre-SCORE) led to flap surgery the same year, increasing to 59.6% (87/146) of assessments after SCORE implementation during 2012-2019. The one-year flap failure rate abruptly decreased from 40.5% (15/37) of the 2009-2012 surgeries to 7.7% (6/78) of the 2013-2019 surgeries (P < .0001). Characteristics of patients by time period, operative status, and flap outcome are presented.

CONCLUSION

After an initial learning curve in tool implementation and subsequent tool refinement, the use of the Minneapolis SCORE before flap surgeries was associated with improved flap integrity at one year. Successful use of the tool requires collaborative problem-solving between the patient and interdisciplinary team.

Reducing pressure with the goal of improving outcomes: a retrospective chart review of cushion evaluations and recommendations at one seating clinic

PURPOSE

To describe the current seating recommendations made by a seating clinic for wheelchair users who presented with a Pressure Injury (PrI) or history of PrI.

METHODS

Retrospective review of electronic medical records of 133 adults who used a wheelchair as their primary means of mobility who had a cushion evaluation during which interface pressure mapping data was documented.

RESULTS

Clinicians adjusted 71% of participants' wheelchair cushions, including 49% who received a new cushion, and 37% of participants' wheelchairs. The most common adjustments besides receiving a new cushion were: addition of an underlay, adjusting the inflation of a cushion, and adjustments to the foot or back support of the wheelchair. Forty-five participants only received adjustments (i.e. no new cushion), while 23 participants only received education and feedback rather than equipment modifications. Those 23 participants had significantly lower Peak Pressure Index (PPI) than those who received equipment modifications (mean [95% CI] 76.7 [59.1, 94.3] versus 111.6 [102.1, 121.2] respectively, p = 0.001). The PPI was reduced by an average of 22.5 mmHg from the initial to final seating system amongst those who received modifications ([13.9-31.0], p<.001).

CONCLUSIONS

The seating clinicians considered interface pressure mapping in their decision-making and effectively reduced interface pressures with their interventions. Cushion replacement is important when someone presents with a PrI. However, adjusting an existing wheelchair cushion and/or seating system provides important additions and alternatives to consider for reducing interface pressure. There is also a role for education about proper use of equipment, weight shifts, and alternate seating surfaces.

Impact of Heterotopic Ossification on Functional Recovery in Acute Spinal Cord Injury

Objective: In spinal cord injury (SCI), heterotopic ossification is a frequent secondary complication, commonly associated with limited range of motion of affected joints, which could lead to secondary disability in activities of daily living. Additionally, heterotopic ossifications might challenge the effect of regeneration-promoting therapies on neurological and functional recovery. This study evaluated the impact of heterotopic ossification on clinical recovery within the first year after SCI.

Methods: The study was conducted as a monocentric longitudinal paired cohort study. Recruitment was based on consecutive sampling in the framework of the European Multicenter about Spinal Cord Injury (EMSCI). Recovery profiles were determined using standardized neurological and functional clinical assessments within the 1st year following SCI. All study participants underwent at least two comprehensive standardized neurological and functional clinical examinations according to the International Standards for Neurological Classification of SCI and the Spinal Cord Independence Measure, respectively. Data regarding the diagnosis and treatment of heterotopic ossification were obtained by reviewing the patient medical records. The most similar “digital twin” from the entire EMSCI database were matched in terms of age, acute neurological and functional status to each individual with SCI, and heterotopic ossification.

Results: Out of 25 participants diagnosed with heterotopic ossification, 13 individuals were enrolled and matched to control individuals. Most individuals presented with motor complete injury (75%). Ossifications were most frequently located at the hip joints (92%) and mainly occurred within the first 3 months after SCI. Individuals with heterotopic ossification achieved around 40% less functional improvement over time compared to their matched counterparts, whereas neurological recovery was not altered in individuals with SCI and heterotopic ossification.

Conclusion: Heterotopic ossification—a common complication of SCI—unfavorably affects functional recovery, which in the end is most relevant for the best possible degree of independence in activities of daily living. Upon presentation with heterotopic ossification, neurological improvement achieved through potential restorative therapies might not translate into clinically meaningful functional improvement. Diagnostic algorithms and effective early prevention/treatment options for heterotopic ossification need to be established to ensure the best possible functional outcome.

Reliability validity and responsiveness of the spinal cord independence measure 4th version in a multicultural setup

OBJECTIVE

To examine the fourth version of the Spinal Cord Independence Measure for reliability and validity.

DESIGN

Partly blinded comparison with the criterion standard Spinal Cord Independence Measure III, and between examiners and examinations.

SETTING

A multicultural cohort from 19 spinal cord injury units in 11 countries.

PARTICIPANTS

Six hundred and forty-eight patients with spinal cord injury.

INTERVENTION

Assessment with Spinal Cord Independence Measure (SCIM IV) and Spinal Cord Independence Measure (SCIM III) on admission to inpatient rehabilitation and before discharge.

MAIN OUTCOME MEASURES

SCIM IV interrater reliability, internal consistency, correlation with and difference from SCIM III, and responsiveness.

RESULTS

Total agreement between examiners was above 80% on most SCIM IV tasks. All Kappa coefficients were above 0.70 and statistically significant (p<0.001). Pearson's coefficients of the correlation between the examiners were above 0.90, and intraclass correlation coefficients were above 0.90. Cronbach's alpha was above 0.96 for the entire SCIM IV, above 0.66 for the subscales, and usually decreased when an item was eliminated. Reliability values were lower for the subscale of respiration and sphincter management, and on admission than at discharge. SCIM IV and SCIM III mean values were very close, and the coefficients of Pearson correlation between them were 0.91-0.96 (p<0.001). The responsiveness of SCIM IV was not significantly different from that of SCIM III in most of the comparisons.

CONCLUSIONS

The validity, reliability, and responsiveness of SCIM IV, which was adjusted to assess specific patient conditions or situations that SCIM III does not address, and which includes more accurate definitions of certain scoring criteria, are very good and quite similar to those of SCIM III. SCIM IV can be used for clinical and research trials, including international multi-center studies, and its group scores can be compared with those of SCIM III.

Impact of complications at admission to rehabilitation on the functional status of patients with spinal cord lesion

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

Aim of the study is to evaluate the impact of complications at admission on the functional status of spinal cord lesions patients.

SETTING

Rehabilitation hospital in Italy.

METHODS

Two hundred and seven patients with complications (mostly pressure ulcers) at admission to rehabilitation were matched for neurological level of injury and AIS grade with 207 patients without complications.

MEASURES

International Standards for Neurological Classification of Spinal Cord Injury, Spinal Cord Independence Measure, Rivermead Mobility Index, and Walking Index for Spinal Cord Injury. These measures were recorded at admission to rehabilitation and at discharge. We also recorded length of acute and rehabilitation stay and discharge destination.

STATISTICS

Student's T test for paired samples, McNemar's chi-square test.

RESULTS

Patients with complications at admission suffered more often from a traumatic lesions. The functional status at admission and discharge of the patients without complications was significantly better than the functional status of patients with complications (Spinal Cord Independence Measure mean difference between the two groups 5.7 (CI 2.8-8.5) at admission, and 10 (CI 5.3-14.7) at discharge). Length of stay was significantly higher in patients with complications. Patients with complications were more often institutionalized than their counterparts (46/161 vs. 20/187, odds ratio 0.4 (CI 0.2-0.7)).

CONCLUSIONS

Complications seem to be more frequent in patients with traumatic lesions. The presence of complications has a negative effect on patients' functional status at discharge and length of stay, and it determines a higher risk of being institutionalized.
